Don't run your server using sudo, it's a huge security hole. Add a separate user (i.e. minecraft), and use chown to change the ownership of the folder/files to your new user. What does your run.sh look like? Post your whole debug.log on a paste site, and link to it here, summarizing errors is typically not helpful.

So do you mean like how fences work? If so, I'd take a look at how fences do it

If you are having an issue, you should start a new thread and post logs, and explain your issue. Asking people if they figured out something on threads that are 1+ years old won't get you help very fast.

Try clicking the +Show All Versions button, and then when you point to the little i next to the installer link, there is a direct download link. See if that works for you.

Post the debug.log from a crashed run to a gist and link it here, it may give some pointers to where things are breaking

The debug.log should be in the logs folder of your game installation folder. If you are using the curseforge client, you may need to add/change a setting to get it to generate. Unfortunately I don't know the specifics to that, as i don't use it myself. For a paste site, I use gist.github.com myself, but there are plenty of others, I forget what other ones are "good". Basically a place to paste the log so you're not making a post that's pages and pages long on the forums. Plus it's usually easier to read on an external site vs here on the forums.

Post your entire debug.log to a paste site, and then post the link here; it should have information that will help find what the issue is.

Looks like you may have some fabric mods in there, those won't work with forge. Start by removing any mod that has the word "fabric" in the filename.

This one jumped right out at us: I think this one might mean you need to update your Java to a more recent Java 8:

I feel as though looking at the code for the nametag would give you something to work with, isn't that used on entities to give them names? Honestly never used one before lol, but if it were me, that's where I would start.

Check thread dates, this guy has prob given up/moved on since this post is nearly 2 years old

If you remove valkyrienskies does it work?

That's a Fabric log, this is the Forge forums.

When you make a change, if it is still not working, post new logs for further help.

There are examples of capabilities on the forums and in the forge docs as well as the forge github that you could use to get started. Poke around some. You can use this to get started: https://docs.minecraftforge.net/en/latest/datastorage/capabilities/ Try some stuff, write some code and share a link to it, it's like bait when fishing, you'll get a bite faster/more bites than an empty hook!

If it were me, I'd probably take a look into capabilities, and add whatever the item handler capability is called (been a hot minute since I've tinkered with them, so no idea if they've changed) to the mobs I wanted when they are spawned into the world. Give it a try, if you run into problems, post your code (pref to a working github repository) for further help. Good luck!

The way this reads, you're asking how to stop and start the server. Just type stop and press enter at the server console, and it will stop the server. Then run whatever command executes the server (often times a batch file, ending with .bat) to start it back up. If that's not what you mean, then I don't think you can "refresh" the server without wiping stuff out, and more or less starting the world over.

You should make your own thread with your issue, instead of posting on someone else's old post. But it looks like you are missing mods that mods you have require.

Looks like you are missing some mods that other mods require.

That does not look like a complete debug.log. You should post it to a paste site like hastebin or something, and then post the link to it here. However, I would remove optifine and see if that helps.

Have you made an item? That's the first step, an item that does nothing that you can hold in your (off)hand. After that, I guess it somewhat depends what passive effect you are looking for. Will this need to be applied on equip/removal? Or is it something that can be detected elsewhere (i.e. damage-taking event, checking for totem equipped, then reducing dmg)

Are you using the curseforge launcher? If so, you will need to go into the settings and enable the debug.log. I do not use the curseforge launcher, so cannot tell you the exact steps for how to do so.

Those logs do not look complete, they look as though they've been cut off. That second log doesn't even have a crash in it. When you have a lot of things and need to find the one(s) that are problematic, there's a method for doing it that's easier than 1 by 1: Remove half of the existing things, and put them aside. Run the program / game. Does the issue still exist? If YES: Repeat from step 1 with the current things. IF NO: Swap out the current things with the ones set aside, and repeat from step 1. Repeat this process until the problematic thing/s have been found.

Apologies, not sure how I thought it was still there, that line was from the old log, sorry. Broken or conflicting mixin(s). Honestly I can't tell which mod(s) exactly are doing it, so unless someone else knows, you'll have to trial and error remove mods and test to figure out which ones aren't working together. The joys of mod developers directly modfiying the minecraft code, weeee
